Normal-state magnetic susceptibility in a bilayer cuprate
The magnetic susceptibility of high-T_c superconductors is investigated in
the normal state using a coupled bilayer model. While this model describes in a
natural way the normal-state pseudogaps seen in c-axis optical conductivity on
underdoped samples, it predicts a weakly increasing susceptibility with
decreasing temperature and cannot explain the magnetic pseudogaps exhibited in
NMR measurements. Our result, together with some experimental evidence suggest
that the mechanism governing the c-axis optical pseudogap is different from
that for the plane magnetic pseudogap.Comment: 5 pages, 2 figure
Conformal Field Theory Approach to the 2-Impurity Kondo Problem: Comparison with Numerical Renormalization Group Results
Numerical renormalization group and conformal field theory work indicate that
the two impurity Kondo Hamiltonian has a non-Fermi liquid critical point
separating the Kondo-screening phase from the inter-impurity singlet phase when
particle-hole (P-H) symmetry is maintained. We clarify the circumstances under
which this critical point occurs, pointing out that there are two types of P-H
symmetry. Only one of them guarantees the occurance of the critical point. Much
of the previous numerical work was done on models with the other type of P-H
symmetry. We analyse this critical point using the boundary conformal field
theory technique. The finite-size spectrum is presented in detail and compared
with about 50 energy levels obtained using the numerical renormalization group.
Various Green's functions, general renormalization group behaviour, and a
hidden are analysed.Comment: 38 pages, RevTex. 2 new sections clarify the circumstances under
which a model will exhibit the non-trivial critical point (hence potentially
resolving disagreements with other Authors) and explain the hidden SO(7)
symmetry of the model, relating it to an alternative approach of Sire et al.

Conducting Cooperative Cases
The power of case studies has been well-documented. Most facilitators use the widely known whole-group Harvard discussion model. However, a cooperative case approach serves as an effective alternative or supplementary approach. This article, which uses-appropriately-the example of a cooperative learning case study, provides a detailed look at the cooperative case study method, including its rationale and value, creative group formations, and facilitation guidelines

Cooperative Learning in Higher Education
Research has identified cooperative learning as one of the ten High Impact Practices that improve student learning. If you’ve been interested in cooperative learning, but wondered how it would work in your discipline, this book provides the necessary theory, and a wide range of concrete examples.Experienced users of cooperative learning demonstrate how they use it in settings as varied as a developmental mathematics course at a community college, and graduate courses in history and the sciences, and how it works in small and large classes, as well as in hybrid and online environments. The authors describe the application of cooperative learning in biology, economics, educational psychology, financial accounting, general chemistry, and literature at remedial, introductory, and graduate levels.The chapters showcase cooperative learning in action, at the same time introducing the reader to major principles such as individual accountability, positive interdependence, heterogeneous teams, group processing, and social or leadership skills.The authors build upon, and cross-reference, each others’ chapters, describing particular methods and activities in detail. They explain how and why they may differ about specific practices while exemplifying reflective approaches to teaching that never fail to address important assessment issues
